AVR-III series is the high precision and intelligent automatic voltage regulator, that is our company self-research and latest newly products. It has newly developed colorful displayer, which can directly show the working performance of proudcts. It takes smart, ligtness, high efficiency, wide stabilize, no waveform distortion, high cost performance of AVR-II. AVR-III can be widely used in family, factory, laboratory and hospital, etc.1, Input Range: 125V~270V( 4 relays) 100V~270V(5 relays) 80V~270V(6 relays) above is 8% degree of accuracy. If theDegree of accuracy is different, the quantites of relay will be changed also, for example input 176V~264V, the degree ofAccuracy is 5% and 5 relays. 2, Accuracy of voltage stabilization: 220± 8% 3, Frequency: 50/60Hz4, Low-voltage protection: 188V± 4V, after low-voltage protection, the output will renew when output voltage run up to 195V.5, Over-voltage protection 243± 4V6, over-temperature protection: 120° C, after over-temperature protection, the output will renew when the temperature fall under 80° C.7, Short time delay(default setting): 5s; Long time delay( select by push-button switch): 255s.8, Reaction time( voltage stabilization time) ≤ 200ms9, Overload protection: The overload proetcion start when it exceed 120% rated input current( Load Detective Tiem 2s)If protected, the output will be back after 10 sec. But after repeated 5 times, no automatic output anymore. You need to shutdown the unit by hand, then also power on again manually.FAQ:Q 1. What's the payment term?A. We accept TT, 30% deposit and 70% balance agaisnt copy of BLQ 2. How's the delivery time?A. Usually it will take about 25 days for productionQ 3. Tell me the standard of package?A. For the small capacity, it use carton, but for big capacity, we should use strong wooden case for protection.Q 4. What kind of material of transformer?A. We have two types, one 100% copper and the other is copper with aluminum. It depends on your requirment. In fact, those two have no difference if normal work well. Only except the longlife. Copper is better and also higer price.Q 5. Could you offer Form A or C/O?A. It totally not a problem. We can prepare relative documents to forgin affairs office or other office to apply for this certificate.Q 6. Would you accept to use our logo?A. If you have good quantity, it absolute no problem to do OEM.Q 7. We want to know month capacity.A. It depends on which model. For example for relay type small capacity, month capacity can reach near 20000PCS and big capacity near 3000PCS.Q 8. Where is your market?A. Our products are popular in Russia, indonisia, Philippines, Italy, America, Pakistan and so on. Some of them are our regular customers and some of them are developing. We hope you can join us and make mutural benifit from our cooperation.Q 9. Does the inverter connect with solar system?A. Yes. Because of the unique feature which combine invert, charge and AC auto-transfer switch into one complete system, made inverter not only connect with solar system, also could be used in officer equipment, household items, power tools ans etc...Q10. What kind of certificate you have?A. Our company already achieve ISO, CCC, and for products, we have CE, SONCAP, GOST, UL(pending).
